The aquarium features a custom-built 5.5-meter diameter acrylic dome that offers an 'inside-out' view of the reef.
The facility uses an advanced life-support system capable of processing 2.2 million liters of water every hour.
The circular design eliminates corners, which helps prevent stress in schooling fish by allowing them to swim continuously.
The lighting system is programmed to mimic natural sunlight cycles, including lunar phases to encourage coral spawning.
It houses a specific 'rehabilitation zone' for injured marine life found in local Hong Kong waters.
The Grand Aquarium is the centerpiece attraction of Ocean Park Hong Kong, featuring a massive 5.5-meter wide acrylic viewing dome. It houses over 5,000 fish representing more than 400 species in a multi-level circular tank design. The facility utilizes a spiral walkway that allows visitors to descend through different ocean depths, mimicking a gradual underwater transition. It is home to endangered species such as the scalloped hammerhead shark and the giant grouper. The aquarium features a massive 13-meter wide reef lagoon viewing panel to provide expansive marine vistas. It serves as a conservation hub for research on marine biodiversity in the South China Sea. The architecture is designed to reduce light pollution for the animals while providing high visibility for guests. It represents one of the largest aquarium tanks in Asia by volume.

Visit the viewing dome area during off-peak hours to avoid the crowds that gather for photos.
Walk the spiral path slowly to notice the changing fish species as you descend from the surface level to the deep-sea section.
Bring a polarized lens for your camera to reduce reflections on the large acrylic panels.
Do not attempt to touch the glass or tap on the tanks, as this causes significant stress to the aquatic animals.
Flash photography is strictly prohibited to prevent disturbing the marine life; keep voices low to reduce vibrations against the glass.
